That doctrine has worked. 2006 to 2023 is the longest period of time without conflicts on this scale since before 1970. Until 2006 there were significant showdowns at most every 5 or 6 years.

The doctrine also is targeting infrastructure for the purpose of denying it to Hezbollah, which is utilizing it to support their fighting. Otherwise, per the wikipedia link on this doctrine, the doctrine has reduction of civilian casualties baked-in:

"in the first stage targets were attacked which formed an immediate threat, and in the second stage the population was evacuated for its protection, and only after the evacuation of the population were Hezbollah targets attacked more broadly."
